A picturesque lake surrounded by forest and greenery. 

There are lots of trails to explore and handy barbecue facilities around. A perfect spot for a picnic in a good company. In stark contrast to the rough, dark lava fields, the quiet and green Hvaleyrarvatn Lake area offers an idyllic spot to spend an afternoon or take a morning stroll. Fir trees stretch across the gently sloping mountain, the silver and blue lake ripples, and a simple path attracts. Protected from the winds, local flora abounds, draping the landscape in a wash of greenery. In recent years, the Forestry Association of Hafnarfjörður helped revive the area with a sustained tree-planting campaign. With help from the townspeople and local schoolchildren, their efforts continue today. 

A comfortable two-kilometre walking path circles the small tranquil lake. Trails also lead away from the water toward the hills, looping their way through the hushed forest and mossy undergrowth. From breaks in the treeline, it's possible to catch sight of the cone-shaped Keilir Mountain in the distance. Also tucked along the paths are a memorial grove, a scouting centre, and of course, dozens of pleasant spots where one can stop to rest and gather serene memories. 

The lake is right next to Íshestar where you can ride the Icelandic horse in the amazing area on excellent riding paths.
